using stack 

#include   
#include 
#include 

int main()
{ 

    std::stack st;
    char *words= "this is a test";
    char * temp =   (char *)calloc(1, sizeof(*temp));
    int size1= strlen(words);
    int k2=0;
    int k3=0;
    for(int i=0;i<=size1;i++)
    {
       temp[k2] = words[i];
       k2++;
        if(words[i] == ' ')     
        {  
            k3++;
            if(k3==1)
                temp[k2-1]='\0';

            temp[k2]='\0';
            st.push(temp);
            k2=0;           
        }
        if(words[i] == '\0')
        {
            temp[k2]='\0';
            st.push(temp);
            k2=0;
            break;
        }               
    }

  while (!st.empty())
  {
       printf("%s",st.top().c_str());
        st.pop();
  }
